Can someone help me with the second question at the bottom? I'm a bit confused about what it is trying to say and what I need to do Question 2: What do you expect to be the wavelength of sound at 21.6°C if the frequency is 800 Hz?

answer: (431,2)

step-by-step explanation:

answer; equivalent to a one(1) horsepower motor;

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
